UG(Unigraphics NX) is a product engineering solution produced by Siemens PLM Software Company, which provides digital modeling and verification means for users' product design and processing. Unigraphics NX provides a mature solution for users' virtual product design and process design needs. UG is also the abbreviation of user guide and Universal Grammar.

This is an interactive CAD/CAM (Computer Aided Design and Computer Aided Manufacturing) system with powerful functions, which can easily realize the construction of various complex entities and shapes. At the beginning of its birth, it was mainly based on workstations. However, with the development of PC hardware and the rapid growth of individual users, its application on PC has grown rapidly and has become the mainstream application of 3D design in mold industry.
